Elecsys immunoassay systems using electrochemiluminescence detection.

Electrochemiluminescence (ECL1) has recently been applied as detection technology for immunoassay systems from Boehringer Mannheim. In particular, the combination of ECL with universally coated micro particle technologies results in fast assays with very high sensitivity and broad measuring range. This is achieved by optimised selection of the electrochemically active "substrates" (Ruthenium chelates and tris-propylamine, TPA). Advantages of this novel application are discussed and the Elecsys 2010 system is described, which is a full automated analyser with full random access capabilities and suitable for the full immunoassay menue. In addition it features an innovative reagent information transfer technique, fast STAT function and continuous sample loading.
